  The wastewaters containing organic and inorganic pollutants after many industrial processes such as metal plating, mining, textile, alloy, battery and industrial chemicals, are often discharged to environment. Heavy metals among these pollutants have highly stable, toxic, non-degradable and carcinogenic characters. They affect not only ecological system, but also human health and many life forms. Therefore, these contaminants should be eliminated or reduced to allowable levels before releasing to environment. Most of heavy metals have toxic character even at low concentrations of about 0.1-0.3ppm. Treatment technologies such as filtration, ion exchange, precipitation, electrodeposition, reverse osmosis, sedimentation, and adsorption have been applied for removal of heavy metals from aqueous solutions. Adsorption is one of the most common and widely applied methods to eliminate the metal ions from waste solutions because of its simplicity and cost effectiveness. Activated carbon, clay minerals, ion exchange resins and various agricultural residues can be used as adsorbent materials in this process [1-3].

  Determination of optimum conditions of crystal violet dye adsorption on almond shells

  Almond shells are considered as agricultural waste. In this study almond shells were chosen as effective adsorbents for removing Crystal Violet (CV) from dye solutions. The experimental data was analyzed via the Langmuir, Freudlich and Tempkin isotherm models to obtain isotherm model for the system and the data shows that the Langmuir isotherm model fitted best. Also, the thermodynamics parameters such as ΔH0, ΔG0 and ΔS0 were investigated. The results of the study show that almond shells are efficient and advantageous economically for removing CV from aqueous solutions. The maximum adsorption capacity was found to be 1.1375mg/g on almond shell. Adsorption kinetic studies indicate that the adsorption data can be represented by a pseudo second order model.
